We recently moved into a '96 mobile home and have developed an
interesting problem. The storm door opening is narrowing at the
bottom.
The frame doesn't seem to have moved (there is a metal threshold
between
the door frame sides), but now the door is too small for the
opening.
The storm door frame is tight to the wooden frame. We have been in
the
trailer since early November and have not had a problem. We have
been
having generally warm weather (above freezing), but recently had
near
zero temps lately and are in a warming spell again, up to 50 today.
Any
ideas would be welcomed!

Any chance that it's a cheap door and IT is swelling?

Aluminum swells?

I didn't seem Aluminum mentioned anywhere.

Then I'd agree that the ends of the trailer may be drooping and
squeezing
the frame.

how about frost heave ?

The ground isn't frozen. In fact, it started after the temps went above
freezing. Trouble is, the door frame width is locked in by the threshold.
There is no sign of any compacting of the wood frame against the aluminum
threshold. The main door is still a good fit. It didn't change, only the
storm door.

P.S. The previous owner put insulation inside the skirting except for half
of each end. When it was near zero overnight it was fairly warm under the
trailer.

That it was warm under the trailer doesn't necessarily imply the
ground under the supports didn't freeze/thaw. The symptom after the
warmup after cold is pretty typical of a minor heave movement. If the
blocking is just sitting on the ground, wouldn't be at all surprised
if it moved some after a spell of zero-degree weather.

If it isn't related to something overall, then the conclusion has to
be something on the frame itself or the mounting to which it fastened
moved.
